    摘要: The present invention relates to a suturing thread for providing a more efficient lift procedure, and provides a suturing thread for a facelift and a body lift, wherein the suturing thread is made of a polymer material and has a plurality of conical protrusions or a plurality of funneled protrusions formed on an outer circumferential surface of a main thread of the suturing thread.

    摘要: Absorbable monofilament fibers and self-retaining sutures with high tensile strengths have been developed. The straight pull tensile strengths of the absorbable self-retaining sutures closely approximate, equal or exceed the average minimum knot-pull tensile standards set by the United States Pharmacopeia (USP). These higher strength absorbable self-retaining sutures can therefore be used either without needing to oversize the suture for a given procedure, or by oversizing the self-retaining suture by no more than 0.1 mm in diameter. In one embodiment, the absorbable self-retaining sutures are made from poly-4-hydroxybutyrate or copolymers thereof.
    Methods for producing absorbable self-retaining sutures that have high tensile strengths and pronounced sheath-core structures wherein the sheath is harder than the core are also provided. The self-retaining sutures may be made by spinning and orienting a monofilament fiber of poly-4-hydroxybutyrate or copolymer thereof and inserting retainers in monofilament fibers.
